Great sale and got battery life well design speaker

This is a replacement of the Onyx Studio 5 and I LOVED that speake but it was stolen and this speaker is no different. It gives great bass but isn't over powering. At the same time it's clear as well. The only con I have is my old speaker lasted about 12 hours before I had to plug it in. This speaker only last about 8 hrs. However, this isn't a big deal to me. One last thing is that the speaker is more powerful while plugged in but I think that's obvious. It's still a great speaker to me.

Sound quality for Harmon Kardon is great. The battery doesn't quite last the full 8 hours. But being able to pair 2 speakers together is an amazing feature. We pair the 2 that we own and put on on the charger in one part of the house and then carry the second to where we are and then we switch them when needed.

Excellent sound quality. I love this thing so much

Harman Kardon - Onyx Studio 6 Portable Bluetooth Speaker - Black

The speaker is a hard mix between good and decent at best. In my opinion its more of a brand purchase then quality, loudness is pretty good but the fact that you cant see how much charge it has at any given moment is pretty inconvenient. Also had the battery run out in about 2 1/2 - 3 hours at full blast and a full charge which just seems a bit low.

I was looking for a wireless speaker for outdoors. This one was on sale. It sounds great! It is substantial enough that it won’t blow over in the wind and I don’t have to worry about a little rain. Would definitely recommend at the sale price.

loud and bassy. sometimes i can literally see this speaker vibrating things i have near it

Overall great for the brand. Still a big fan of the studio 3 the best!

Unreal sound quality for a speaker this size. Regular price is steep but sale price makes it competitive with inferior speakers from other brands. Love the handle and auxiliary input. 10/10 would buy again.

This speaker, by far is the best speaker that I've ever owned. its a 10 in my score card. Not to mention I SAVED $280.00 BUYING IT AT BEST BUY!!! THIS speaker puts most peoples car systems and home theater systems to shame, with ease.

Best portable speaker I've used. Good bass, but it can get lost in a larger room. The waterproofing is nice, so I wouldn't be afraid to use this next to my pool.

By far the best portable speaker I’ve ever owned. Has really nice base. The speaker is more powerful if plugged in. It loses a tiny bit of steam when it’s running off the rechargeable battery. But not too noticeable.

Battery life short, sounds great great volume easy to look at

Straight out the box an all I can say is wow x 2. It paired up with my very quickly and the sound quality of it blew me away. Trust me its worth buying. Again totally blown away. Very exceptional speaker.

It sounds amazing. Its perfect for my college dorm for relaxing movie nights. I dont have a TV so it works perfectly woth my laptop. Highly recommend.

The sound it’s nice, its a good product and like .

Fair value wireless Bluetooth speaker. Not as loud as I expected it to be but it has a clean sound. I feel like the battery life is not so great on this item. I find it more useful to keep the speaker plugged in which is not as convenient as I would have hoped for. Weight is neutral considering the power involved with this speaker.

If you are going to use it with a MacBook, DO NOT BUY IT. The sound is good, maybe too much bass if you do not have an equalizer, but, definitely, Mac and Harman Kardon do not get along. I am not going to explain one more time why, many other people did already. Thank you.

This is the second one I have purchased. I purchased the first one over a year ago. I'm impressed by the all around sound quality. I like the build quality as well. Very solid. You pay for what you get.
